Answer:
(Fatwa: 888/888=M/1429)
One has to give interest to the bank in case of loan, and as taking interest is haram, giving interest is also haram except in exigent cases. Therefore, first of all, you should try to get interest-free loan. If after due efforts, one fails to get it and he is in dire need of house then in state of exigency one can take loan from bank but only as much as needed.
